95024 Intradermal allergy test Medicare reimbursement rates in Washington

Small amounts of diluted allergenic extract are injected into the superficial dermis, often on the upper arm. Sites are typically read about 15 to 20 minutes later for an immediate wheal-and-flare reaction. Common extracts include dust mite, mold, pollen, and animal dander. Intradermal testing is more sensitive than percutaneous prick testing and may follow negative or unclear prick results when the history still suggests an inhalant allergy. Allergists commonly order and interpret these tests in an office, where nursing or allergy staff may place and read them. Nearly all Medicare volume for this code is in the office setting.

Report one unit for each intradermal allergen test performed and interpreted; do not count the reading as another test. Interpretation and the written report are included. Documentation should identify each allergen and its concentration or dilution, the reading time, wheal-and-flare measurements, and the interpretation. Practice expense accounts for most of the office value, reflecting extracts, supplies, and staff time; physician work represents 4% of the office total. Venom, drug, sequential and incremental airborne-allergen, and delayed-reaction testing have separate codes.
